Understanding CRA Categories

The CRA classifies products into four risk-based categories, each with different conformity assessment requirements.

Default Category

Products within CRA scope that do not fall into the important or critical categories.

Self-Assessment (Module A)

Confirm the product's category and scope

Important - Class I

Product categories listed in Annex III, Class I.

Conditional

Self-assessment depends on Article 32 conditions

Important - Class II

Product categories listed in Annex III, Class II.

Third-Party Assessment

Check permitted routes and exceptions

Critical

Critical product categories listed in Annex IV.

Additional Requirements

Check applicable acts and certification schemes

What Does This Mean For You?

Self-Assessment (Module A)

You declare conformity yourself without external auditor involvement. However, you must still:

  • •Create and maintain Technical Documentation
  • •Perform risk assessment and vulnerability testing
  • •Issue EU Declaration of Conformity
  • •Affix CE marking
  • •Define and meet the applicable security support period

Notified Body Audit

A designated conformity-assessment body examines the evidence required by the selected procedure. Discuss:

  • •Module B: Type examination of design and documentation
  • •Module C: Production conformity verification
  • •Assessment schedule and availability
  • •Fees for the agreed scope and assessment procedure
  • •Certificate scope, validity, and any continuing obligations

Start with the applicable requirements

Annex I requirements and the product's cybersecurity risk assessment inform the engineering work. The chosen conformity-assessment route determines the additional evidence and review process.

Frequently Asked Questions

What are CRA Annexes III and IV?

Annex III lists important product categories in Classes I and II. Annex IV lists critical product categories. The applicable conformity-assessment route depends on the product category and the conditions in Articles 8 and 32, including any applicable standards, certification schemes, and exceptions.

What is a Notified Body?

A Notified Body is a conformity-assessment body designated by an EU Member State for specified assessment activities. Its role depends on the applicable procedure. Scope, fees, timing, and required evidence need to be agreed with that body.

What should I check for a Class II product?

Class II products generally require third-party conformity assessment or an available, applicable European cybersecurity certification scheme. Article 32 includes specific routes and an exception for qualifying free and open-source software. Confirm the product category and applicable conditions before choosing a route.
